Patented Aug. 12,1936 I PATENT OFFICE OF DETROIT, MICHIGAN, ASSIGNOR '10 BUCKEYE IRON AND BRASS WORKS, OI DAYTON, OHIO, A OOBPQBATION O! 0310 SIGNAL Application filed September 28, 1927. Serial No. 221,581.

My invention relates to signals.

It is the object of my invention to provide a signal particularly adapted for use on fire en ines, ambulances and other ublic vehic es which must carry signals or use on their emergency missions. It is also designed for use at railroad crossings and in other locations where the certainty of its operation and its continuing function is essential to protect life and property.

It is my object to provide a construction which may be easily and quickly repaired and replaced; a structure in which the arrangement is such that when certain of the elements such as one or more of the light bulbs becomes inoperative it will not render the remaining-elementsinoperative so that a likelihood of a complete cessation of the func: tioning of the complete signal will be small.

In particular it is my object to provide a structure in which the standard or support and a common switch may be permanently mounted upon a support adjacent the railroad track, while the complete operating structure may be detachably mounted so that a new unit can be quickly installed and brou ht into functioning almost immediate y.

It is a further particular object to provide a plurality of completely independent lights and circuits for the lights so that if one light becomes injured or the circuit is broken it will not interfere with the remainder of the lights.

It will be understood that in operation, as on an ambulance, the lights will have their beams projected forwardly of the vehicle by reason of the combination of the beams and any colors which may be imparted to the beams, the vehicle will be,dist1n ished as a public vehicle as compared wit a private vehicle.

Referring to the drawings:

' Figure 1 is a front elevation.

Figure 2 is a side elevation.

V Figure 3 is a wiring diagram.

Figure 4 is a rear elevation with the cover removed.

Figure 5 is a section on the line 5-5 of' Figure 4, showing the unitary mounting of the motor, gearing, contact shaft, operating shaft, arms and lights u on a common supporting plate which is etachably attached to the sup orting housing and standard that is attache to the ground or to the vehicle.

Referring to thedrawings, 1 is a standard adapted to be installed in the ground or attached to a vehicle. The standard has detachably mounted thereon a box, consisting of a bottom, top and sides open on either end. This box is designated 2 and isattached to the standard by the bolts 3. The box carries a switch, generally designated 4, having a switch button on the outside of the box.

A reaninspection plate 6 is detachably mouiited upon the box by suitable screws, while a bed plate 7 forms the front of the box and carries the following mechanism: The motor 8, the standard 9 for the contact arm, the contact arm 10, the contact shaft 11, the driving sleeve 12, the driving ears 13 and 14, the light spider 15. and the lights 16. This front plate is detachably mounted on the box by the screws 17.

The motor 8ldrives the worm 14, which in turn drives the worm wheel 13. This worm wheel is'g connected to the shaft 12 which is rotatably mounted in the bearing sleeve 18. This sleeve 18 is supported in the relatively long bearing hub 19 of the'front plate 7 and may be easily replaced when broken or worn. An oiling well 20 is provided for oiling this hearing. The light spider 15 is connected by any attaching means, such as a set screw 21, to the driving sleeve 12. This driving sleeve is hollow and carries the contact rod 11, which engages with the contact finger 10 on the inside of the box. The other end of the contact finger 10 is attached to but electrically separate from the supporting standard 9 on the front wall 7. This also contsitutes a terminal 22, to which is connected the wire 23. The other wire 24 is connected to a terminal 25 on this contact finger. The terminal 25 is connected by the wire 26 to the switch 4. The other side of the switch is connected by the wire 27 to the source of current.

Referring to the light spider which comprises the arms 29, it will be found that within of w The wires 30 lead out of this rum from the that slpider is ahbllow drum 28 onthe exterior ich are mounted the s 'der arms 29.

contact rod 11 and connect with the lights 16.

The lights 16 are mounted b v the bolts 31 in any desired position upon t e spider.- Customarily, these lights are adjustedso as to direct their beams at an angle to the axis of the contact shaft of this apparatus.

It will be apparent that when it is desired to substitute new mechanism, that the dis connection of the wires 26 from the terminal 25 and the removal of the bolts or screws retaining the front plate 7 on the box will enable the removal of the (plate and all the operating parts as, a unit an the substitution therefor of a complete new operating outfit. The lights 'will then again be ready to revolve and function. V

The diagram shown in Fig. 3 shows the ground connections for the wires 32, 33, which lead from the motor and lighting circuits.

The construction is such that ice, snow and? dust cannot interfere with its operatiota ms Damage to any one of the lights will *1,- jure the operation of the rest of the light I desire to comprehend within my invention such modifications as may be clearly embraced within the claims and the scope of the invention.

Having thus fully described my inven -ion,

what I claim is new and desne to secur by Letters Patent, is

1. In a signal, the combination of a support, a casing supported by said support, said.

casing having a front face plate provided with a bearing, a hollow shaft supported by said bearing and extending through theface plate, a plurality of substantially radially arranged arms supported by said hollow shaft, light means mounted on eachlarm, an electrical motor mounted on said face plate, drive means between said motor and said shaft, a

terminal block mounted on said face plate, 45

and electrical connections for said motor and said light means including a conductor extending through said hollow shaft and a stationary contact arm mounted at one end of said block and bearing against the end of the conductor at the other end of said hollow shaft.

2. In a signal, the combination of a support,

a casing mounted on the support, said casing having a removable face plate, a hollow light supporting shaft and a motor shaft mounted on said face plate, said shafts being in a substantially horizontal plane but at right angles to each other, a motor mounted on said motor shaft, and a light mounted at one end of said light supporting shaft, a terminal block mounted on said face plate, a conductor extending through said hollow shaft and a stationary contact arm mounted at one end on said block and bearing against the end of the conductor at the other end of said hollow shaft.

3. Ina sig'nal,the combination of a support, a casing mounted by said support, a motor having a shaft mounted within said casin upon a removable face plateforming part- 0 said casing, a light supporting shaft mounted at right angles to the face plate and motor shaft, means for supportin said motor shaft in a plane parallel to the ace plate, a worm gear on the light supporting shaft parallel to the face plate, and a worm-meshin with said worm gear on the motor shaft, an light supporting means mounted on one end of said ight supporting shaft.

4. In a signal, in combination, a casin motor means mounted in the casing, a she having a plurality of arms, signal means mounted on said arms for projecting a plurality of light beams in a substantially horizontal direction, adjustable means on the arms for varying the angularity of the rojected beams with respect to the axis of t e shaft "said shaft having a portion located within and another portion located outside of said casing, and 'a drive connection from said motor to said shaft.

5. In a signal, in combination, a casing, motor means mounted in the casing,-a hollow shaft, a member on said shaft having an open ended cavity and provided with apertures, said member having a plurality of arms, signal means mounted on saidarms for project-- ing a plurality of light beams in a substantially horizontaldirection, adjustable means on said arms for varying the angularity of the projected beams with respect to the axis of said hollow shaft, said shaft having a portion located within and another ortion outside of said casing, a drive connection from said motor to said shaft, a conductor located within said hollow shaft having one end extending into said member, and a plurality of conducting wires connected to one end of said conductor and passing through said apertures for connection to said signal means.

In testimony whereof, I aflix my signature.
